Description
Technical Field
[0001] This utility model relates to the field of automotive seat technology, specifically to a multi-functional automotive seat cushion lifting mechanism. Background Technology
[0002] Car seats are crucial components connecting occupants to the vehicle body, serving not only to provide support but also directly impacting the driving experience, safety, and health. From static fit to dynamic cushioning, from basic functions to intelligent interaction, car seat design integrates technologies from multiple fields, including ergonomics, materials science, and mechanical engineering. Currently, the demand for comfort and the diversification of seat functionality provide drivers and passengers with a better experience.
[0003] Currently, car seats on the market offer a variety of functions, but regardless of whether they are manually adjustable or electrically adjustable in four or six directions, their core adjustment dimensions are concentrated on the seat's forward and backward movement, backrest angle tilt, and overall height adjustment. The adjustment logic is centered on "optimizing the riding posture," and independent movement control of the seat cushion has not been achieved. Furthermore, the key function of independently lifting the seat cushion, which is related to space adaptation and ease of use, is still lacking in existing technologies, and cannot meet the diverse needs of users in various scenarios. Therefore, a multi-functional car seat cushion lifting mechanism is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a multi-functional car seat cushion lifting mechanism to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional car seat cushion lifting mechanism, comprising a tray, a drive motor, and a seat cushion tray. A tray slide is fixedly connected to the tray, and a drive gear slide is installed on the tray slide. A drive shaft is installed on the output shaft of the drive motor, and a drive gear is installed on the end of the drive shaft away from the drive motor. A rotating shaft gear is meshed on the drive gear.
[0006] As a further preferred embodiment of this technical solution: the pallet slide provides a moving path for the drive toothed plate slide, and is used to reduce moving resistance and improve transmission efficiency. The drive toothed plate slide supports the drive toothed plate and the drive toothed plate fixing frame respectively. At the same time, the drive toothed plate is used to transmit power and torque and ensure transmission accuracy.
[0007] As a further preferred embodiment of this technical solution: the device is powered by a drive motor, and the power and torque are transmitted through a rotating shaft gear, ensuring the stability and reliability of the power transmission.
[0008] As a further preferred embodiment of this technical solution: a seat cushion rotating shaft is fixedly connected inside the rotating shaft gear. The seat cushion rotating shaft is used for the connection between the rotating shaft gear and the two seat cushion side guards, as well as to ensure the stability of rotation.
[0009] As a further preferred embodiment of this technical solution: two pivot support frames are symmetrically installed on the tray and on both sides of the tray slide, which support the seat cushion pivot and fix the position of the seat cushion pivot.
[0010] The two ends of the seat cushion pivot are respectively inserted into two pivot support frames.
[0011] As a further preferred embodiment of this technical solution: two drive tooth plate fixing frames are symmetrically fixedly connected on the drive tooth plate slide rail and on both sides of the drive tooth plate. The drive tooth plate is fixed and supported by the drive tooth plate fixing frames, thereby providing a stable installation foundation for the drive tooth plate.
[0012] As a further preferred embodiment of this technical solution: two cushion rotating arms are symmetrically installed on the seat cushion seat basin, and two seat cushion side guards are symmetrically inserted through both ends of the seat cushion rotating shaft and on the opposing sides of the two rotating shaft support frames. The seat cushion rotating arms connect the seat cushion rotating shaft and the seat cushion seat basin, while the seat cushion side guards protect the core components inside the seat cushion.
[0013] As a further preferred embodiment of this technical solution: the two ends of the seat cushion pivot are respectively fixedly connected to the two seat cushion pivot arms, and multiple connecting rods are fixedly connected to the adjacent side of the two seat cushion side panels. The two separate seat cushion side panels are connected and fixed by the multiple connecting rods. The installation method of the two ends of the seat cushion pivot and the two seat cushion pivot arms forms a firm rigid connection, eliminating the gap and relative movement between the seat cushion pivot and the seat cushion pivot arms, and avoiding energy loss during the power transmission process.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model can fill the functional gap and meet the needs of diverse scenarios. It addresses the problem that existing car seats (whether manually adjustable or electrically adjustable in four or six directions) only focus on the forward and backward movement of the seat, the tilt of the backrest, and the overall height adjustment, without realizing independent movement control of the seat cushion, thus failing to meet the needs of space adaptation and ease of use. By using components such as a drive motor, drive gear plate, and rotating shaft gear, the seat cushion can be lifted independently, filling this functional gap and adapting to the diverse usage needs of users in various scenarios.
[0016] 2. In this utility model, the drive tooth plate slide provides a moving path for the drive tooth plate and supports related components. The drive tooth plate fixing frame fixes and supports the drive tooth plate, ensuring the meshing accuracy between the drive tooth plate and the rotating shaft gear, avoiding transmission deviation. The seat cushion rotating shaft and the seat cushion rotating arm are rigidly connected to eliminate gaps and relative movement, reduce power transmission loss, and ensure that the drive motor power is efficiently transmitted to the seat cushion and seat basin, so that the seat cushion lifts up in a timely manner and runs smoothly.
[0017] 3. In this utility model, the pivot support frame on the tray supports and fixes the seat cushion pivot, preventing it from sagging, bending, or shifting, ensuring the stability of the pivot rotation and the accuracy of its relative position with other components. The seat cushion side guards can protect the core components inside the seat cushion and are connected and fixed by connecting rods, enhancing the overall structural integrity and extending the service life of the mechanism. At the same time, this utility model enables independent adjustment of the seat cushion, breaking through the limitations of traditional seat adjustment. Users can flexibly adjust the seat cushion state according to their needs, improving the convenience and comfort of riding, and meeting the diverse functions of car seats and users' needs for comfort.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Example
[0024] Please see Figures 1-3 This utility model provides a technical solution: a multi-functional car seat cushion lifting mechanism, including a tray 1, a drive motor 4 and a seat cushion tray 11. A tray slide 2 is welded on the tray 1, and a drive gear slide 3 is installed on the tray slide 2. A drive shaft 5 is installed on the output shaft of the drive motor 4. A drive gear 6 is installed on the end of the drive shaft 5 away from the drive motor 4, and a rotating shaft gear 7 is meshed on the drive gear 6.
[0025] In this embodiment, specifically: the tray slide 2 provides a moving path for the drive toothed plate slide 3 to achieve directional power transmission, and also reduces moving resistance and improves transmission efficiency. The drive toothed plate slide 3 is used to support the drive toothed plate 6 and the drive toothed plate fixing frame 10 respectively. At the same time, the drive toothed plate 6 is used to transmit power and torque, and also to ensure transmission accuracy.
[0026] In this embodiment, specifically: the drive motor 4 is used to provide power for the overall operation of the device, and the rotating shaft gear 7 is used to transmit power and torque on the one hand, and to ensure the stability and reliability of power transmission on the other hand.
[0027] In this embodiment, specifically: a seat cushion rotating shaft 8 is welded inside the rotating shaft gear 7. The seat cushion rotating shaft 8 serves two purposes: firstly, it connects the rotating shaft gear 7 with the two seat cushion side guards 13; secondly, it ensures the stability of rotation.
[0028] In this embodiment, specifically: there are two rotating shaft support frames 9 symmetrically connected by bolts on both sides of the tray 1 and on the tray slide 2. The rotating shaft support frames 9 are used to support the seat cushion rotating shaft 8, providing it with a reliable support point and preventing the seat cushion rotating shaft 8 from sagging or bending due to gravity, ensuring that the rotating shaft remains horizontal during rotation. On the other hand, they are used to fix the position of the seat cushion rotating shaft 8, fixing the seat cushion rotating shaft 8 in a specific position, restricting its displacement in the horizontal and vertical directions, so that it can only rotate around its own axis, ensuring the relative positional accuracy between the seat cushion rotating shaft 8 and other components, thereby ensuring the accuracy and stability of the overall transmission of the device.
[0029] The seat cushion pivot 8 has two bearings that pass through the two pivot support frames 9.
[0030] In this embodiment, specifically: two drive gear plate fixing frames 10 are symmetrically welded on the drive gear plate slide 3 and on both sides of the drive gear plate 6. The drive gear plate fixing frames 10 are used to fix and support the drive gear plate 6, thereby providing a stable mounting base for the drive gear plate 6, fixing it in a specific position, so that it maintains the correct posture and position during operation, preventing displacement or shaking due to external forces. At the same time, it helps to maintain the meshing accuracy between the drive gear plate 6 and the rotating shaft gear 7, thereby ensuring the transmission accuracy.
[0031] In this embodiment, specifically: two seat cushion rotating arms 12 are symmetrically connected to the seat cushion basin 11 by bolt threads, and two seat cushion side guards 13 are symmetrically passed through both ends of the seat cushion rotating shaft 8 and located on the opposing side of the two rotating shaft support frames 9. The seat cushion rotating arms 12 are used to connect the seat cushion rotating shaft 8 and the seat cushion basin 11 to realize the action execution, while the seat cushion side guards 13 are used to protect the core components inside the seat cushion.
[0032] In this embodiment, specifically: the two ends of the seat cushion pivot 8 are welded to the two seat cushion pivot arms 12 respectively, and multiple connecting rods are welded to the adjacent side of the two seat cushion side guards 13. The multiple connecting rods are used to connect and fix the two separate seat cushion side guards 13. By means of the above-mentioned installation method of the two ends of the seat cushion pivot 8 and the two seat cushion pivot arms 12, a firm rigid connection is formed, eliminating the gap and relative movement between the seat cushion pivot 8 and the seat cushion pivot arms 12, avoiding energy loss in the power transmission process, and ensuring that the power output by the drive motor 4 is efficiently transmitted to the seat cushion seat 11, so that the seat cushion lifting action responds promptly and runs smoothly.
[0033] Working principle: After the drive motor 4 starts as the core power source, it transmits power to the drive shaft 5 connected to its output shaft. The drive shaft 5 further drives the drive gear plate 6 installed at one end to move, providing the initial driving force for the entire mechanism. The drive gear plate 6 meshes with the rotating shaft gear 7. Under the drive of the drive gear plate 6, the rotating shaft gear 7 rotates accordingly, realizing the conversion of power from linear drive to rotary drive. At the same time, the drive gear plate slide 3 provides a stable moving path for the drive gear plate 6. The drive gear plate fixing frames 10 on both sides fix and support the drive gear plate 6, ensuring the accuracy of the meshing between the drive gear plate 6 and the rotating shaft gear 7, avoiding transmission deviation, and ensuring stable power transmission.
[0034] The seat cushion shaft 8, which is fixedly connected inside the rotating shaft gear 7, rotates synchronously with the rotating shaft gear 7. The rotating shaft support frame 9, which is symmetrically arranged on the tray 1, supports and positions the seat cushion shaft 8, preventing it from sagging or shifting during rotation and ensuring stable rotation of the seat cushion shaft 8. Since both ends of the seat cushion shaft 8 are fixedly connected to the seat cushion rotating arm 12 on the seat cushion 11, a rigid connection structure is formed, with no gaps or relative movement. The rotational power of the seat cushion shaft 8 can be efficiently transmitted to the seat cushion rotating arm 12, thereby driving the seat cushion 11 to lift up.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
